Sprue in-mold cutting mechanism and injection mold applying same

The invention discloses a pouring gate in-mold cutting mechanism and an injection mold applying the pouring gate in-mold cutting mechanism. The pouring gate in-mold cutting mechanism comprises an inclined ejector rod; the cutter is mounted at one end of the angle ejector rod; the moving part is mounted on the outer surface of the mold, and forms a wedge structure with the other end of the angle ejector rod; the output end of the linear driving part is connected with the moving part so as to drive the moving part to do linear reciprocating motion relative to the die, and the linear reciprocating motion of the moving part is changed into feeding or retracting motion of the cutter through the wedge structure; the stroke adjusting end plate is located on the side, away from the linear driving part, of the moving part and provided with an inclined face for limiting movement of the moving part, the position of the stroke adjusting end plate is adjustable, the moving part abuts against the positions, with different
